@ne object of the invention is 1in/providea newl and improved self-heating sad iron capable ofjconvem'ent. construction and use vand possessing specialiieatnres of advantage p Y presented.' reference being vhad'to. the accomp'anving drawings, 1n which:

Eig'ure 1 is a top' view of a sad iron conv 'n accordance with andieinbodving the invention; Fis?. is a vertical longitudinal section of the same on. the dotted line 2 2of Fig. 1; Fig. 3 is a vertical transverse section of the same on the dotted. line 3.#-3 (1f-'Figar 1, and Fig. 4 is a detached bottom View Aofthe cover plate of the iron.

proper inthe construction otiron hereinplesented hat said apertures 13, remainV constantly open. The flanges ,14, afford, convenient air' spaces, behindl which the, apertulles are located; and prevent the charcoal or otherI combustible material from ,y escaping through'l the apertures 13; The, flanges 1,4 also centralize the charcoal -or other combusl'l' material within. the `body 1,0' and aidin enablingv the combustible. material to maintain' a substantiallv uniform temperature throughout saidbody. U The upper edqes of the'. body 1Q presentr uniform horizontal surfaces except at opposite sides. of said body,

Where standards 1 5 are formed, being' QaStIl.- tegrally' with;

the biodv 10 to. receive the transverse rod orv pin 16S by means of; which the cover 11 may be detachably secured lupon the body 10. e

The corer 11 Yis a ,casting having an elliptical outline correspondingivith thel outline of thebody 10 andrecessed at its opposite side edges. as at 16, to 15 extending);VV upwardly from the sideedges of' theL body. 10;' The `cover-11 is of'special importance in securing conveniencev both in the manufacture and use of' the ironV and Vin the attainment of `proper combustion, and

saidcover istormed in its end portions with upwardly erterrclinp,` recesses or chambers 17 apertured at theirupper ends, as at 18', said chambers and apertures extending along both sides .of each end ofthe cover and there preiera'bly7 being three aperturesglS at each side orA eachend of the cover. Atjthe eX- treme ends' of' the, coverk 1l are, provided downwardly extendingy lugs' 19" which enter iit up onl the v standards the endfportion's of the body1 l()y and Serveto vreadilvposition thecover on said the lower side ofthe. cover 11'l are two slidable` damperv plates E20, which v correspond 'Witheach other, and one of which is below one endof the coverV and tbeother below the other end of theV cover and their purpose being to. enable the user of the. iron to requla'te the draft'throueh theopenings 1'8" at the V'ends of' the cover'. l'n Figi.' 4 l illustrate one of the damperl platesl as having. been moved to; a position to close thel openings 18above it; andjtbe'otherdamper plate 20 as moved to a position partlv .uncovering the recess or chamber Udeadingf to the other set of openings ,181 Thermaterial' Oftll@ ,0037er 11 body.

of the cover to form the chambers or recesses 17 which extend along each side of each end of the cover, and the damper plates 20 are secured against the lower face of the cover and are slidable longitudinally so as to entirely or more or less close said recesses or chambers 17, each damper plate 20-being in` dependently in `rection.

Each damper plate 2O is formed with a longitudinal slot 21 clearly indicated by dotted lines in F ig. l, and each slot receives a portion of a rivet 22 which extends downwardly through the cover 1l and the slot 21 and a spring 23 and is upset at its lower end against said spring 23. There are two rivets 22, one for each damper plate 20, and both rivets are utilized, as shown in Fig. 2, in securing the handle supporting bar 24; upon the cover 11, said rivets extending downwardly through said bar, through integral bosses 25 formed on the upper surface of *he cover 1l and through said cover and the slots 2l and Vspring 23 and being upset at their lower ends against said spring. The damper plates 2O are formed with upwardly projecting thumb-pieces 26 which extend upwardly through slots 27 in the cover plate ll, and said thumb-pieces 26 may be utilized for sliding the damper plates 2O frontwardly or rearwardly, as occasion may require. The

thumb-pieces 26 are exposed at the upper side of the cover or plate 11, and hence the damper plates may be adj usted so as to more or less close the chambers or recesses 17 without removing the cover plate from the body of the iron. When the cover plate is not on the body of the iron the damper plates 20 may be readily moved longitudinally by the pressure of the thumb or thumbs of the user The outer end and side portions of the damper plates 20 conform to the edge outline of the cover plate 11, and saidy cover plate-on its lower surface is recessed, as at 28, to a depth about equal to the thickness of said plates 20. Y

The spring 23 is of special importance in that it retains the'damper plates 2O in position against the lower surface of the cover 11, and said spring 23 is a flat leaf-spring slightly bowed and in its normal condition prior to being applied to the iron being more greatly bowed than is represented in the drawings. Then the spring 23 is secured by the rivets 22 it `becomes less bowed than when in its normal condition, and therefore the end portions of the spring 23 become rather firmly pressed against the lower surfaces of the damper plates 20 and serve to yieldingly, though firmly, hold saidL plates up against the lower surface of the cover 11'.

The cover ll is formed at its opposite sides and in line with the inner edges of the recesses 16 with vertical lugs 29, which match vand set against the standards 15 formed on pinl 16 by the Ybody vable in a longitudinal di-l Yagainst the cover,

the body of the iron, as shown in Figs. l and 3, and said lugs 29 andstandards 15 are correspondingly apertured to receive the rod or which the cover is connected with of the iron. The other a pair of flanges 30 which connect the lugs `and strengthen the cover and form between them a channel, as shown in Fig. 2, along which the rod or pin 16 may extend. Y

The invention made the subject hereof was devised shown in the Letters Patentof the United States No. 705,573 granted to me July 29,

`I have found that with the low recesses or chambers 17 at each end ofthe cover and provided with the top outlet openings at each side of each end, the` draft through the iron great efficiency, and said recesses constitute one of the important features of the present invention and apertures` 13. The dampers- 2O arranged close up under the cover and independently slidable aid very much in the draft regulaingly against the lower face of the cover by means of the spring` 23 is important in that the dampers may` yield to variations in teinperature without binding and at all times keep their position. y Y

lV hat I claim as my invention and desire to secure bv Letters Patent, is: M

1. A self-heating ysad-iron. coinprisingaJ hollow body having air inlets in the lower portion of its sides, a cover for said body and a handle on said cover, said cover having a shallow upwardly extending open recess in the lower side of its' end portion and a series of openings along the top of said recess, and'said cover also having on its lower side a slidable damper having an exposedl thumb-piece Yfor more orless closing said recess. j f

2. A self-heating sad-iron comprising a may beV regulated with.

tion, and securing the said dampers yield- -hollow body having a pointed end and air inlets at its lower portion, a cover for and conformi-ng to the outline of said body and having at its rvpointedend a ydraft outlet, a slidable damper on the lower side of said cover having an exposed more or lessclosing said outlet,a spring secured to the cover Iand fiexed against said damper for .yieldingly pressingthe same and a handle on ,said cover, said damper therein'and said spring cured tothe cover by a through said slot.

3. A self-heating hollow body having air inlets in thek lower portion of its sides and a,k pointed end, a cover for and conforming to the outline of said bodyand having at its pointed endand and handle being serivet which extends having a guide slot sad-iron comprising a wm'dly extending open shallow recess and a series of top outlet openings from the sides of said recess, a handle for the iron secured to said cover, and a slidable damper on the lower side of said cover having an exposed thumb-piece for more or less closing said recess.
